PROBLEM TO BE SOLVED: To ensure airtightness of each of cases in connecting electronic parts in the two cases electrically by forming a simple structure. SOLUTION: In electrically connecting a circuit board 12 in a first case 1 and a circuit board 18 in a second case 2, a first elastic part 21 is held between the case 1 and a rear cover thereof while a second elastic part 22 is held between the case 2 and a rear cover thereof, and a connection member 24 is embedded in a connection part 23 between both the parts 21, 22, whereby the member 24 is covered with the member 23 so that the part between both the parts 21, 22 is not exposed to the outside, resulting in securing the airtightness of both the cases 1, 2 sufficiently, and further the structure that the member 24 is embedded in the connection member 24 between both the parts 21, 22 makes the airtight structure simple, leading to reduction in cost. |
